Peter J. Pobgee has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Graphical input apparatus for electrical equipment
    Patent number: 4164622
    Abstract: A graphical input tablet is disclosed in which a sheet of resistive material is stretched across a surface comprising parallel conductors on, but insulated from, a resistive layer. Currents are passed alternately through the resistive layer and means which places the conductors at different graduated voltages. Thus when a stylus used to indicate a point causes the sheet to bridge the resistive layer to one of the conductors, alternate voltages representative of two co-ordinates of the position of the point are developed.
    Type: Grant

  • Graphical input apparatus for electrical equipment
    Patent number: 4149029
    Abstract: A graphical input tablet is disclosed in which the lower surface of a sheet is spaced from the upper surface of a fixed member. Each or both surfaces are formed by parallel conductors but where only one surface is formed in this way the other surface is resistive. Currents are passed alternately through the surfaces to provide voltage gradients, and when a stylus is used to indicate a point, alternate co-ordinate signals for the point are obtained.
